# AOD603

**XBLW** · MOSFETs · TO-252-4L

AOD603 from XBLW, in a TO-252-4L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S1 | passive | Source of the N-channel MOSFET (VDS = 60V, ID = 20A, RDS(ON) < 34mΩ at VGS=10V). |
| 2 | G1 | input | Gate of the N-channel MOSFET (VGS rating ±20V, threshold 1.0V to 2.5V). |
| 3 | S2 | passive | Source of the P-channel MOSFET (VDS = -60V, ID = -15A, RDS(ON) < 86mΩ at VGS=-10V). |
| 4 | G2 | input | Gate of the P-channel MOSFET (VGS rating ±20V, threshold -1.0V to -2.5V). |
| 5 | D1/D2 | passive | Exposed tab labelled D1/D2, carrying the drains of the N-channel (60V, 20A) and P-channel (-60V, -15A) MOSFETs. |

## CAD (KiCad official)

- Symbol: `AOD603`
- Footprint: `Package_TO_SOT_SMD:TO-252-4`
- 3D model: TO-252-4L (KiCad packages3D, STEP)
- 3D model files: `aod603-etched.step` / `aod603-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `aod603.step` / `aod603.glb` are the bare package body.
